Classified documents should always be stored in what type of container when not in possession of an authorized individual?

Classified documents must be stored in a GSA-approved security container when not in possession of an authorized individual to ensure the highest level of protection. GSA-approved security containers are specifically designed to meet strict government standards for security, which include resistance to unauthorized access, physical protection against tampering, and often additional features like alarms or reinforced locks.

Using a GSA-approved container reduces the risk of unauthorized access to sensitive information and aligns with the standards established by the Department of Defense for handling classified materials. This is crucial for maintaining national security and ensuring that sensitive data is only available to individuals with the appropriate security clearance.

While locked drawers or filing cabinets may provide some level of security, they do not meet the specific criteria laid out for the storage of classified materials and may not adequately secure the information from potential threats. Additionally, the notion that a document marked confidential can be left unsecured if not in someone's possession is misleading, as all levels of classified information require appropriate storage measures regardless of their specific designation.
